IGF-1 LR3

IGF-1 LR3 – Long-Acting IGF-1 Analogue for Research Applications

IGF-1 LR3 (Insulin-like Growth Factor 1 Long Arg3) is a synthetic research peptide designed as an extended variant of the IGF-1 protein. It is routinely supplied as a reagent for in-vitro research focused on cell growth, receptor signalling, and metabolic signal transduction.

This peptide features an N-terminal extension and a strategic arginine substitution at position 3, increasing its half-life and enhancing receptor interaction in experimental settings. HPLC-verified for ≥97.8% purity, IGF-1 LR3 is suitable for consistent, reliable laboratory applications.
